Parallelism & Performance: Why O-notation matters
UPDATE: There was a bug in the way the suffix map was built in the original post that lolplz found. I updated this post with that bug fixed, however, the content of the post has not changed significantly.
File locks in bash
For quite a while I’ve been looking for a portable utility that mimics Procmail’s “lockfile” command. I didn’t need all the functionality, just for it to lock a single file and support a retry limit and sleep parameters. I finally implemented one using Bash’s “noclobber” option.

Pratt Parsers
Some time ago I came across Pratt parsers. I had never seen them before, and I found them quite elegant.

To make a long story short, I have been a busy little bee for the last few days and managed to build a reasonable proof-of-concept.
